LedgerDex is built on top of the 0x Protocol, which is an open standard that has been used by a number of independent applications such as decentralized exchanges (DEXs) and relayers.
In order for different applications built on top of the 0x Protocol to cooperate with each other (such as sharing each other's order books), 0x has also provided a Standard Relayer API (SRA) specification, which defines a number of API endpoints as well as rules for implementing and accessing these endpoints.
LedgerDex currently provides a REST API that implements 0x's Standard Relayer HTTP REST API Specification v3.
If you are interested in accessing LedgerDex's API, you can find the API reference at 0x's SRA GitHub repo:
https://github.com/0xProject/standard-relayer-api/blob/master/http/v3.md
The root URL for LedgerDex's REST API is: https://api-v3.ledgerdex.com/sra/1/v3/
For example, the endpoint for getting a list of LedgerDex's fee recipients is:
https://api-v3.ledgerdex.com/sra/1/v3/fee_recipients
The current rate limit for our API is 60 requests per minute.
